Be it known that I, WALTER P. MURPHY, a citizenof the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car- Roofs, of which the following isa specifica-..

' 3 tion.

This invention relates particularly to.

freight car roofs of the type made of heavy gage metal roof-plates supported on a skele .Hton roof substructure composed of carlines' and purlins, although it is applicable to roof substructures havingno purlins,-and to lighter "sheet metal roofs having roof sheets supported on roof sheathing boards.

- these plates to have-a limited amount of" This invention is an improvement in 1,139,363, dated May 11, 1915.

Among the principal ob ects of my in- "vention are to make a water-tight car roof of substantial construction which-will withstand hard service and will'not require re- I movement relative tothe roof substructure;

'to provide an improved form of construction in which any water that may happen to leak through any of the seams between the roof plates will be guided down to the caves and not be allowed to enter the car.

Other objects of'ithe invention relate to 1 :thefclet'ail'construction of the, roof, as will ap ear more fully hereinafter. r

he invention consists in the construction and in the arrangement and combination 7 of parts hereinafter more fully set forth.

Ingeneral, my invention comprises a metal roof formed of overlapped roof-plates which extend from eaves to eaves'. and are secured together by being, riveted along their meeting edges. The roof-plates are supportedupon a skeleton roof frame'work and are secured to this frame work near the ridge. At the eaves, the roof-plates are held down by a fastening which permits them to have a limited amount of movement longitudinally ofthe car.

By reason of this construction, as the car 'weaves'and racks in service, the seams of the roof will not be torn or injured, because the roof-plates are fixedly secured to the substructure at,

the ridge only and are free to adjust themselves to the different positions which the parts of the substructure may take.

Referring to the drawings, particularly Figs. 1 to 9, the car shown therein comprises side frame members 11. to which are attached the car siding 12. The side plates 13, which extend lengthwise of the car along the tops of the sides thereof are made of metal bars of a Z cross-section. Each of these side plates 13 is disposed so that the middle web is vertical, the top flange faces in, and the bottom flange faces out. The carlines' 14 are substantially inverted T- shape in cross-section and are arranged parallel to each other transversely of the car and are spaced about four feet apart. The

carlines 14 are placed so that their horizontal flanges 15 are at the bottom and their central webs16 extend upward. The carlines 14 are curved upward in the middle in the arc of a circle' and their ends are riveted to the top flanges of the side plates 13. The horizontal flanges 15 of the carlines are bent up along a line intermediate secure the carlines to the side plates.

horizontal flanges of the carlines support the ends of purlins 18 Which'are securely riveted thereto.

The roof. plates 20 are made of heavy gage metal, and are supported directly on the 'purlins. Each of the roof plates 20 is bent at one of its side marginal edges to form an upwardly extending flange 21 inverted U-shape in cross-section. The'opposite side marginal edge of each plate 20 is bent to form an upwardly extending flange 22 inverted U-shape in cross-section, the

outer edge of which is extended below the plane of the plate to form a drip edge 23. The side marginal flanges 21 and 22 of adjacent plates are overlapped and fastened together by rivets 24 to form arched seams.

The rivets 24 are placed in a line a few inches apart in the side of the seam above the drip edge 23. When the roof plates are placed in position, each of the arched seams straddles a carline. A space is left between I the top of each carline and'the under side of the corresponding arched seam. Each of the drip edges 23 is directly above one of the rivets 28.

troughs 17 in a carline and serves to carry any water which may leak around the rivets 24 or between the lapped portions of the plates down away from the under faces of the plates 20 to the eaves.

The ends of the roof plates at the eaves are doubled under to form end flanges 25. These flanges 25 are loosely hooked into the doubled-over inner edges 26 of the flashing strips 27 which extend lengthwise of the car at the eaves. The flashing strips 27 are bent to fit closely against the outside faces of the side plates and are fastened thereto by The lower edges of the flashing strips 27 project over. the lower flanges of the side plates 13 to form drip edges 29. These drip edges 29 shed any water which may run oif the roof plates clear of the sides of the car. The upper portions of the flashing strips 27 are cut at points opposite the ends of the carlines to form holes 30 to allow the water in the carline troughs 17 to drain through the flashing strips and over the eaves.

The end caps 31 are placed over the ends of the arched seams and carlines to prevent any water from getting into the car at these points. These end caps 31 have aprons 32 which hang down over the lower flanges of the carlines and cover the holes 30 in the flashing strips 27. The end caps 31 are riveted to the roof plates at the top of the arched seams. By this construction the roof plates are fastened to the roof sub- 1 structure, at the ridge only and the eaves edge of the roof plates are held loosely in position by the flashing strips 27 This allows the ends of the roof plates to have a certain amount of free movement at the leaves in their own plane, and permits the roof plates to accommodate themselves to the distortions of the car frame, such as occur in service.

The running boards 33 are bolted to saddles 34, each of which straddles a carline and r an arched seam for a short distance on each .side of the ridge. Each running board saddle 34 has two pairs of depending lugs 35 stamped out of the top part near each end and bent down to embrace the underlying arched seam. At the points where these lugs embrace the seam, U-shape pieces 36 are inserted under the arch of the seam straddling the top web 16 of the carline. Rivets or bolts 37 are passed through the depending lugs 35, the sides of the arched seam and the Y carline web to secure all of these parts firmly together. In this waythe weight which may be placed on the running boards is supported by the carlines.

The modified construction illustrated in Figs. 10 to 12shows the application of my construction for draining off any water which may pass throughthe seams of the On each side of the car the roof plates 38 I extend 'a short distance beyond the outer edge of thetop flange of the side plate 13, and are bent downward to form drip flanges 42. Flashing strips 43, having'drip edges '44, are fastened by rivets 45 to the outer sides of the side plates 13. The inner edge 46 of each flashing strip 43 is bent-and extended underneath the drip flange 42 and the body of the corresponding roof plate 38.-

An end cap 47 is placed over the -end of each seam and. is fastened to the seam and the carline by a through rivet 48. Each end cap 47 has an apron 49 which hangs'down over the lower flange of'the carline and is fastened firmly to the side plate by rivets 50. strips 43 opposite the ends of the carlines are cut away to allow the carline troughs 17 to drain off the eaves.
